Appli ati n fil d June 6, 1903. Serial No. 160,366. (No model.)

To a, whom, it may concern.-

Be it known that we, ARTHUR BRAZILLA FROST, manufacturer, of the city ofOleveland, in the county of Ouyahoga, State of Ohio, and HARRY LOUISFnos'r, manufacturer, and ALEXANDER ROBERTSON, machinist, of the town ofWelland, in the county of Welland, in the Province of Ontario, Canada,have invented certain new and useful Improvements in Barbed Wire forFences, of which the following is the specification.

Our invention relates to improvements in barbed wire for fences; and theobject of the invention is to devise a barb and means for holding itfrom longitudinal displacement on the strand which will not be liable toinjure animals by contact therewith; and it consists, essentially, of adouble barb made of two pieces of wire interlocked and formed with acentral hole, so that they will readily turn on the supporting-wire,such wire being swaged on each side of the barb, so as to prevent thelongitudinal displacement, as hereinafter explained.

Figure 1 is a perspective view of portion of a strand of a fence,showing our improved barb and means for holding the same in place. Fig.2 is a cross-section. Fig. 3 is an enlarged detail of the barb from theone end. Fig. 4: is an enlarged detail from the opposite end. Fig. 5 isa view from the opposite side to that shown in Fig. 1.

1n the drawings like letters of reference indicate corresponding partsin each figure.

A is the main strand of wire, which is provided with projections a,swaged or otherwise pressed out of the bottom of the barb, as indicated.

B B is the double barb. The portion B is provided with a barb at eachend and passes intermediate of its length circularly, so as to form acentral hole, being separated intermediate of its length, so as to passto a position diametrically opposite Where the opposite point ends. Thecoil thus formed is separated intermediate of its length laterally. intothe space so formed extends the portion B, which is provided with a barbat each end, such portion B passing around the wire and to the outsideof the circular part of the main portion B when it is twisted around theportion N atb and passes then outwardly crosswise to the barbed end 7/,the pointed end of the portion B being substantially at right angles tothe barb of the portion B, which it straddles. It will thus be seen thatthe two wires or portions B and B, forming the double or reallyfourminted barb, are interlocked and form a central opening B throughwhich the wire extends.

The barbs may be formed separately from the main wire A and placedthereupon and the projections to afterward formed, or the barbs may beformed upon the main wire A, as may be desired and found mostconvenient.

The main object of our invention is to produce a barb which when ananimal comes up against it will recede or revolve on the main wire. Thebarb will prick the animal; but instead of having a tendency to tear theanimal in its endeavors to get away it will partially rotate or give andfree itself from the hide of the animal, and thereby not be liable toinflict a severe flesh wound.

In every case the barbs will have a tendency to recede from the animal,altl'iough they will punish him sufiiciently to make him keep away fromit.

\Ve preferably use our barb on a coiled-wire strand, the pitch of whichis of course very great.

hat we claim as our invention isv 1. In a barbed wire, the combinationwith the main wire, of the portions B and B, the portion B passingaround the wire in a coil and having the points oppositely set and thecoil slightly separated, and the portion B iitting into the separationbetween the coil and passing around the wire and twisted around onepointed end, the points of portion B being substantially at right anglesto the points of the portion B as and. for the purpose specified.

2. A double barb comprising the portions B and B, the portion B beingformed with a coil intermediate of its length slightly sepa rated, andthe portion B being formed with a coil intermediate of its lengthpartially inserted in the separation of the aforesaid coil,

volutions and twisted around one end of the portion B, the points ofboth portions being arranged at different angles, as and forthe purposespecified.
